Three real residuals questions

From the practice pool, not the mock papers — each with the reasoning that produces the answer.

92 practice questions sit on this single topic — enough that it is worth working through by topic rather than meeting it scattered through a unit review.

100% of them come with a figure. Reading the graph or diagram correctly is most of the work here before any content knowledge applies.

98% test a single AP skill: Using Probability and Simulation. That makes this topic unusually predictable to prepare for.

Using Probability and Simulation · with figure

The visual summary is based on trial summaries. Which panel shows a wave-like residual pattern?

  1. APanel A
  2. BPanel Bcorrect
  3. CPanel C
  4. DPanel D
  5. EPanel E
Why B is correct

Panel B shows a wave-like residual pattern.

This is a strictblind AP Statistics figure item. The stem withholds the data needed to choose an answer, and the answer must be determined from the residual_plot rendered from render_spec. The matching residual pattern must be identified from the displayed panel, not from the option text. The answer key is recomputed from the structured answer_rule.

Using Probability and Simulation · with figure

A display summarizes tracking readings. Which panel shows random scatter around zero?

  1. APanel A
  2. BPanel B
  3. CPanel Ccorrect
  4. DPanel D
  5. EPanel E
Why C is correct

Panel C shows random scatter around zero.

This is a strictblind AP Statistics figure item. The stem withholds the data needed to choose an answer, and the answer must be determined from the residual_plot rendered from render_spec. The matching residual pattern must be identified from the displayed panel, not from the option text. The answer key is recomputed from the structured answer_rule.

Using Probability and Simulation · with figure

The graph presents rating values from a neutral data set. Which panel shows a curved residual pattern?

  1. APanel A
  2. BPanel B
  3. CPanel C
  4. DPanel Dcorrect
  5. EPanel E
Why D is correct

Panel D shows a curved residual pattern.

This is a strictblind AP Statistics figure item. The stem withholds the data needed to choose an answer, and the answer must be determined from the residual_plot rendered from render_spec. The matching residual pattern must be identified from the displayed panel, not from the option text. The answer key is recomputed from the structured answer_rule.
